I need two wedding monogram designs for the same client

Contest Brief

Wedding Monogram Design.
The first will be the couple's pre-wedding initials: L and M.
The second, for after the ceremony, will include their last name initial: A or the full last name: Armstrong
It has to be very modern - think W Hotel style.

Their style is....Minimalist, clean, crisp, fresh, trendy whilst elegant and beautiful for wedding stationery.
Sans Serif fonts, no cursive - unless you can make it look amazing!
The couple are very fashion conscious & cool :)
